A legal challenge by three major beverage companies to the Northern Territory's cash for containers recycling scheme is set to be determined in the Federal Court.
The court will consider the application by Coca-Cola Amatil, Schweppes Australia and Lion Pty Ltd in Sydney on Tuesday.
The companies oppose the NT scheme which involves a 10 cent deposit on drink purchases, refundable when the container is returned to a designated recycling agent.
The scheme has been running for just over a year and is similar to one that has been operating in South Australia for decades.
Coca-Cola says if the challenge was successful it would move quickly to reduce its drinks prices in the NT after they were raised to cover the costs of the scheme.
